Just did a trial setup of my FastMail account in the Gmail app on my Android 'phone (Moto X Style/Android 6.0) without problem.
I don't use the Gmail app myself (quite happy with AquaMail Pro), but of course I had to use the Gmail app to set up my Gmail address to keep Google happy, but then I disabled the sync on the Gmail app, and use AquaMail Pro for all my e-mail accounts.
I followed the setup from the link posted to the FastMail configuration for the Android 'phone, and the instructions there worked OK for me.
